A successful treble bet involves selecting the winner of each of the three nominated treble races.
The bettor can select any number of possible winners in each leg. The cost of the bet is calculated by multiplying the number of selections in each leg. Treble betting is popular in the United Kingdom. A treble bet is not an official tote betting product and is mostly used by UK betting sites to allow clients to combine three single win bets into a treble, much the same way that a multi bet would.
The treble bet horse racing example shows a bet ticket where the bettor has selected: one horse to win the first leg, four to win the second leg and six horses to win the third and final leg. The cost of the bet is $24, as there are 24 possible winning combinations.
Treble betting is not hugely popular and so is not offered by many bookies, especially as it is not a formal bet type with the tote.
Treble betting is not available in Australia with pari-mutuel betting. However, the quaddie, a longer version of a treble bet involving four legs, is. Also, available to Australian racegoers is double betting in the form of a daily double. Both bet types are very similar to treble betting.
